<p>A method and apparatus for triggering and measuring electrochemiluminescent phenomena using a voltage waveform applied at the voltammetric working electrode which improves the precision and accuracy of measurements. This waveform has a decreasing scan rate in the range of voltages for which electrochemiluminescence is triggered and is substantially sinusoidal in shape in this range. The waveform results from locating the reference electrode (20) of a potentiostat in close potential proximity to its counter electrode (16), and applying a uniform scanning voltage waveform at the reference electrode (20). The waveform also can be synthesized digitally, converted to analog form, and applied directly to the working electrode (18) with the reference electrode (20) in close potential proximity to the working electrode (18).</p> |
